A simple model of ultrasound propagation in a cavitating liquid. Part II: Primary Bjerknes force and bubble structures [PDF]
, 2012 In a companion paper, a reduced model for propagation of acoustic waves in a cloud of inertial cavitation bubbles was proposed. The wave attenuation was calculated directly from the energy dissipated by a single bubble, the latter being estimated ...
